Gabor Veres commented on MODCLUSTER-102:
----------------------------------------

Successfully applied the patch and built, but the results are just the same. On my current testbed I can generate 404's by simply clicking refresh in the browser at a rate of 4/second... During this one-thread testing this seems to be the relevant part of error.log:

Please note, that the url I'm using here is not the load-balancer demo application, but another webapp hosted on the worker nodes. The behavior is the same as of the demo app.
